In the top equation, move 4x to the other side so that y is by itself. You can do this by subtracting 4x from each side: y = 8 - 4x

Now, substitute this value in place of y in the second equation:

5x + 2(8 - 4x) = 13

Distribute the 2 through the terms in the brackets:

5x + 16 - 8x = 13

Move 16 to the other side of the equation and collect like terms:

5x - 8x = 13 - 16

-3x = -3

Divide each side by -3 to get x by itself:

x = 1

Now substitute this value in place of x in the first equation:

y + 4(1) = 8

y + 4 = 8

y = 4

I hope this helps!

2y + 8x = 16

5x+2y=13

subtract first equation by second.

3x = 3

x = 1

insert answer into first equation

2y + 8 = 16

2y=8

y=4

Check using equation 2.

5+8 = 13

therefore x=1, y=4

1) y + 4x =8

You divide 4x from both sides , soo.. 4x divided by 8 will equal 2.

y=2

2) 5x+2y=13

you subtract 2 from 13

5x=11

divide 5 from both side and you will get 2.5
